/*
 * NAME
 * 	sigpending02.c
 *
 * DESCRIPTION
 * 	Test to see the the proper errors are returned by sigpending
 * 	
 * ALGORITHM
 * 	test 1:
 * 	Call sigpending(sigset_t*=-1), it should return -1 with errno EFAULT
 *
 * USAGE:  <for command-line>
 *         -c n    Run n copies concurrently
 *         -e      Turn on errno logging
 *         -f      Turn off functional testing
 *         -h      Show this help screen
 *         -i n    Execute test n times
 *         -I x    Execute test for x seconds
 *         -p      Pause for SIGUSR1 before starting
 *         -P x    Pause for x seconds between iterations
 *         -t      Turn on syscall timing
 *
 * HISTORY
 *	02/2002 Written by Paul Larson
